BACKGROUND Despite growing number of intraocular lens power calculation formulas, there is no evidence that these formulas have good predictive accuracy in pediatric, whose eyes are still undergoing rapid growth and refractive changes. This study is intended to compare the prediction error and the accuracy of predictability of intraocular lens power calculation in pediatric patients at 3 month ...

PURPOSE Hip fractures are associated with poor prognosis in elderly patients partly due to the high rate of postoperative complications. This study was aimed to investigate whether the surgical risk calculator is suitable for predicting postoperative complications in elderly Chinese patients with hip fractures. METHODS The incidence of postoperative complications among 410 elderly patients wi...

in this paper, a fundamentally new method, based on the denition, is introduced for numerical computation of eigenvalues, generalized eigenvalues and quadratic eigenvalues of matrices. some examples are provided to show the accuracy and reliability of the proposed method. it is shown that the proposed method gives other sequences than that of existing methods but they still are convergent to t...

Pulmonary arterial hypertension (PAH) is a severe and often deadly disease, originating from an increase in pulmonary vascular resistance. Its prevention and treatment are of vital importance to public health. A group of medical researchers proposed a calculator for estimating the risk of dying from PAH, available for a variety of computing platforms and widely used by health-care professionals...

A superposition/convolution GPU-accelerated dose computation algorithm (the Calculator) has been recently incorporated into commercial software. The algorithm requires validation prior to clinical use. Three photon energies were examined: conventional 6 MV and 15 MV, and 10 MV flattening filter free (10 MVFFF). For a set of IMRT and VMAT plans based on four of the five AAPM Practice Guideline 5...

background: we investigated the efficacy of a mobile-based  bolus advisor app in comparison with the usual multiple daily  injections (mdis) in diabetic patients. materials and methods: in a nonrandomized, controlled clinical trial, 62 diabetic patients  were selected to receive a 12-week intensive glycemic control by either a mobile-based bolus advisor (app) or mdi in the usual manner.we compa...

The accessibility of datasets from the Internet coupled with mathematically enabled software and technologies such as graphing calculators which include data analysis capabilities, place in the hands of students and teachers tools that have the potential to create a rich learning environment for the study of statistics. Further, the advent of graphing calculator peripherals such as Texas Instru...

A cosmology calculator that computes times and distances as a function of redshift for user-defined cosmological parameters is available at http://www.astro.ucla.edu/∼wright/CosmoCalc.html. This note gives the formulae used by the cosmology calculator and discusses some of its implementation. A version of the calculator that allows one to specify the equation of state parameter w and w is at AC...

To facilitate the adoption of low-carbon farming practices in Europe, the European Commission developed a carbon calculator that assesses greenhouse gas (GHG) emissions and recommends mitigation actions suitable for each farm. The Carbon Calculator, which quantifies GHG emissions based on international standards for life cycle assessment and carbon footprinting, delivers carbon footprint result...
